[Also in Group XXII] In a method of producing a pattern of an object 1 which it is desired to reproduce, the object is partially immersed in a mouldable material A, Fig. 9, which is converted to a solid state or allowed to solidify, further mouldable material B, Fig. 10, is added and solidified, the female mould parts thus formed are separated and the objects removed, a parting plate 15 interposed between the said mould parts, Fig. 11, and a third mouldable material introduced into the mould cavity or both sides of the parting plate. The third mouldable material is then solidified or allowed to solidify and the pattern and its associated parting plate removed. The object 1 is first mounted in a hole in a plate 4 by means of a ceramic or other filler, which plate and filler, which may be composed of a number of parts, are removed after the mouldable material A has solidified. Holes 17 in the parting plate connect the pattern portions on both sides of the plate. Suitable mouldable materials are wax, slurrys, thermoplastic or thermo-setting resins or compounds including such resins, and low melting point alloys. For example the material A may be a low temperature melting alloy, the material B a wax, and the third some other suitable material. Alternatively the materials A and B may be low melting alloys having different melting points and the third material a wax. The pattern may be used to produce a partible ceramic or other high temperature resisting mould. To prevent adhesion the object, the parting surface of the material A, and the mould cavity may be treated with a parting medium such as graphite. The first Provisional Specification refers to the use of multi part patterns with the parts made of different materials such as materials which melt at different temperatures, or one part of frozen mercury and one of a low melting point alloy, or a parting strip of e.g., nylon. The method is stated to be suitable for the manufacture of dies and tools and in one embodiment, the object to be reproduced with the help of the finished die or tool is partially immersed in a low melting alloy, a parting medium applied to the surface of the alloy and mercury or an alloy containing a high proportion of mercury poured into the container to totally immerse the object. The mercury is then frozen, the mercury and alloy parts removed from the object, invested by dipping in ceramic slurry and then run out. Specification 802,134 is referred to.

Title: Apparatus for and method of controlling relativistic charged particle beam distribution and transport
IPC: H01J5/18
Filed: 1971-08-04
Abstract: 1351689 Automatic current regulation ENERGY SCIENCES Inc 4 Aug 1971 [18 Aug 1970] 36594/71 Heading G3R [Also in Division H1] The flux of charged particles leaving a gasfilled chamber is regulated by sensing the beam current and varying the gas pressure accordingly. As shown, an intense pulsed beam of charged particles is produced by applying negative high voltage pulses P to a collector plate 2 secured to a cold cathode 3. The beam passes from a high vacuum chamber 3' to a low pressure drift chamber 8 through a first window 7 and emerges from an exit window 10. The windows may be titanium foil. A charge sensor 15 or Rogowski loop sensor 14 feeds back a signal through a circuit 23 to control a butterfly valve on a port 9 to adjust the pressure in chamber 8 such that magnetic fields generated by the beam particles and by surrounding plasma cancel each other, resulting in a constant uniform beam density. An integrated charge monitor, responsive to electrons back-scattered from window 10, may be located in the wall of chamber 8. In modifications, the chamber 8 may take the form of a flattened cone with conducting vanes to improve the current density uniformity of the selfdistributed beam, Figs.2, 3 (not shown). Also, a preformed plasma may be maintained by setting up a continuous gas discharge in chamber 8. The supply for the discharge may be controlled by feedback circuit 23 to provide additional control of the current density distribution, Fig.4 (not shown).

Each package is first displaced on to a package-forming roller adjacent a delivery tray and maintained there until an empty tube is placed between packageforming rollers and then, in the second stage, the package is released to roll into the delivery tray. Sliver passes to reciprocating guide funnel 4 over a sliver plate 6 which is pivoted to swing under the influence of a rod 7 in relation to the reciprocations of the funnel 4, which has a motion parallel to the package-forming rollers 10, 11. In the first doffing stage, the package 9 by its own weight is displaced to rest on the roller 11 only when released by a pair of solenoid-controlled plates 19 under the influence of a doffing counter. An empty tube 16 is placed between the rollers 10, 11 as described in Specification 872,955 and weighting blocks 38 are transferred to the empty tube. The package 9 is then released again to roll in to the delivery tray 22 and throw-over levers 41 carrying a roller 42 are actuated to tear the sliver and fold it over the empty tube. To assist the tearing of the sliver, the rotating guide funnel 4 may be momentarily stopped. Reciprocation of the funnel 4 parallel to the rollers 10, 11 is effected by a cam 48, Fig. 2, in conjunction with an arm 12 carrying the funnel 4 and pivoted to arms 13, 14.
